A team of academic researchers revealed that an undocumented feature in Intel CPUs was leading to vulnerabilities that could compromise the safety of the system.
- A new fault injection attack dubbed Plundervolt was developed to compromise Intel SGX secrets.
- An attacker could manipulate the voltage of CPUs to trigger computational faults in a controlled manner.
- The security of the Intel SGX trusted execution environment was challenged since it protects cryptographic secrets and isolates sensitive code execution in memory.
